Touch demo board

Microchip has added to its mTouch capacitive touch devices with the PICDEM touch sense 2 demo board, supplied with the updated software development kit populated with a 16-bit PIC24FJ256GB110 microcontroller which features an integrated charge time measurement unit (CTMU) peripheral for fast capacitive touch sensing.

This is claimed to be the world’s first 16-bit MCU family with USB on-the-go. The board and supporting materials provide a complete platform for implementing capactiive touch-sensing interfaces, without the need for external components. Additionally, with the family’s peripheral integration and 256 KB flash memory, and the company’s free software libraries, embedded designers can use a singles MCU to implement a wide variety of additional user-interface functions, including QVGA touch-screen displays, speech-based audio prompts and USB connectivity.
